IMHO, the 18's suit the car better. I also would expect that those 19" stradale wheels are massively heavier than the 18" Challenge wheels. How do the 19's fit? And what does it drive like? I also notice that the colour difference between the 19" and 18" is quite a bit different, or maybe it's the light? The brightness of the 18" look better too.
I guess I need to explain. I have a set of 4 19" challenge wheels and a pair of 18" fronts. That's why I asked the question like I did. No other options are available to me, so other alternatives don't matter. Gotta put tires on something and gotta sell something, but let's not get started on tires.
I like the 19's at all 4 corners. The rear end of the 348 is not so proportionally large that the staggered look makes sense. To my eyes, the staggered option looks a bit off. Great wheels either way. Looks great on your car.
If they are all challenge wheels then go 18 front 19 rear. Why? 1- 18 front better for bad LA roads 2- 18's have more available track tire sizes and slicks too for the few trackdays you do 3- which wheel with tire combo is lighter? let's weigh them 4- are the track widths the same? Go with the bigger one. Or will one size allow tweeking the track width with spacers better?
Never thought about staggered, interesting..... The 18" challenge wheels are 8" wide up front so you can run a 235 or a 245/40 up front. As far as tires, been looking at those myself- a economy priced set is at Tire Rack Continental' s on sale, the DW, a set in 235/40/18 with a 285/35/19, is just over $800... They do not have a 295/35/19, so may be best to stay with 235 up front. A set of 245/40/18 with a 295/35/19 rear in the Michelin Super Sport are a tad over $1300 right now - I think a $70 rebate is on right now, pays for the freight. You got me thinking about this staggered thing Bruce......
